<p>Provides a field to store bytes as PostgreSQL large objects.
PostgreSQL offers support for large objects, which provide
stream-style access to user data that is stored in a special
large-object structure. They are useful with data values too large
to be manipulated conveniently as a whole.</p>
<h5 style="padding-top: 10px;">Psycopg2 for Python</h5>
<p>
Psycopg allows access to the large object using the
<code>lobject</code>
class. Objects are generated using the
<code>connection.lobject()</code>
factory method. Data can be retrieved either as bytes or as Unicode
strings.
</p>
<p>
Psycopg large object support efficient import/export with file
system files using the
<code>lo_import()</code>
and
<code>lo_export()</code>
libpq functions.
</p>
<p>Changed in version 2.6: added support for large objects
greated than 2GB. Note that the support is enabled only if all the
following conditions are verified:</p>
<ul>
<li>the Python build is 64 bits;</li>
<li>the extension was built against at least libpq 9.3;</li>
<li>the server version is at least PostgreSQL 9.3
(server_version must be >= 90300).</li>
</ul>
<p>
If Psycopg was built with 64 bits large objects support (i.e. the
first two contidions above are verified), the
<code>psycopg2.__version__</code>
constant will contain the lo64 flag. If any of the contition is not
met several lobject methods will fail if the arguments exceed 2GB.
</p>
<p>This module allows the LargeObject Field to be previewed by
the Preview Dialog. It is installed automatically with the MuK
Preview Dialog module. It has no direct visible effect on the
system. It allows LargeObejct fields to be previewed by the Preview
Dialog.</p>
